PRELIMINARY
5.1 Cleaning
Regular cleaning will extend the life and performance of the DView. Before cleaning, be sure
to unplug the power cord from the power outlet.
Cleaning the Display Panel
Body and Remote Control
Do not under any circumstances use solvents such as benzene or thinner to clean the DView.
Doing so may cause deterioration or peeling of paint from the display or remote control unit.
Wipe the display and remote control gently with a soft cloth. In case of excessive dirt buildup,
dampen a soft cloth with a diluted neutral cleaning detergent. Wring the cloth thoroughly,
then wipe the component and dry it with a dry soft cloth.
Cleaning the ScreenAfter dusting, wipe the screen gently using a soft cloth (cotton, flannel etc.). Do not use tissue
or coarse fabric. The screen surface is easily scratched; do not rub it or hit it with a hard
object.
If you clean the surface of the screen with a wet cloth, do not allow water droplets on the
surface to enter into the product; this may cause a malfunction.
Cleaning the VentsAs a general rule, use a vacuum cleaner about once a month to clean the vents on the rear
panel of the display of dust buildup (set the vacuum cleaner to its weakest setting when
doing this). If not removed, accumulated dust can cause the internal temperature to increase,
resulting in possible breakdown or fire.

Table 5-1 provides some general guidelines for troubleshooting problems you may
encounter with the DView. If the suggested solutions fail to resolve the problem or if you
encounter an issue not described here, please contact your Vidikron dealer or Vidikron
